DD is 6yrs, ASD/SPD and constipated
she has the typical limited diet that lots of autistic DCs have, but she does eat wholemeal bread, jacket potato (incl the skin), orange juice and ripe bananas
she eats very little, so i make sure she has lots of fats as well as fibre, but i think her issue started with not drinking enough, she needs to be prompted to drink, and so far, school have been very lacksadaisical about this
On the GPs advice, she is taking 15ml of lactulose twice daily, and has been since last Thursday, but things don't seem to have improved.
she bleeds fresh blood when she poos, and gets extremely distressed about this. she really resists me touching her when she's in pain, and i'm now nursing a nice bruise where she kicked me because i asked to see her bottom 
she has just been for a poo now, and i think she's got slight damage to her perineum, it's very red and i'm not sure if it's bleeding
any suggestions i can use tonight until i can try to get her another GP appt?
